Hybrid Meeting Audio - 2 cameras/2 mikes?

I am on the board of a medium sized community organization, and we hold quarterly meetings.  The meetings look like a city council meeting + online zoomers.  So there is the 6-member board at a head table, with an audience ranging from 30-100 depending on attendance, sitting in chairs facing the table.  We have a camera/microphone/speaker that captures the Board video and audio.  I need to plug in a second camera for the audience (suggestions welcome).  But my real question is:  Can I use a (hopefully wireless) microphone that can be handed to audience members so they can ask questions, with clear audio feeding into the Zoom meeting?  Thoughts?  Suggestions?
